Rooi@` CONSTRUCTION.

Application filed August 9, l1926.v serial No. 127,990.

The present invention relates to new and .useful il'nprovements in roof constructions, whereby an easily assembled, inexpensive design is obtained. vention are to produce a simple form of construction which can be laid by one man and can be easily applied to any form of roof construction. VIt is also a'n object of the in vention to devise a form of roof construction which will not warp or buckle and by which relatively inexpensive material can be used.

These and other objects will be apparent to those familiar with this art. It will be. understood that while one form of the invention only is shown, various changes and modifications may be made therein without departing from the essential features thereof as set forth in the appended claims.

In the drawings, in which the form pre-A ferred by me at the present time is shown,

Figure l is a cross-section through a typical roof construction;

Figure 2 is a transverse section on the line 2-2 of Figure l; f

Figure 3 is a plan;

Figure t is an enlarged section of one portion of the roof; A

Figure 5 is a plan of the construction at the point of attachment to a purlin; and

Figure 6 is a section on the line 6-6 of Figure 5.

In the construction shown, the numeral l represents the purlins supporting the roof Structure. Over the purlins' is laid the Sheet metal 2 which constitutes the basis or foundation of the roof structure. This metal base is provided with a plurality of parallel grooves or channels 3 separated by corresponding ridges 4 connected by inclined walls 5. Vhile the tapering or inclined walls are shown in the various views forming grooves in the general rhomboid configuration, other forms of grooving may be substituted therefor.

In each of the grooves is laid a wooden filler piece 6 of substantially the shape to lit therein, being held in position by any suitable fastening devices, illustrated here as nails 7. It will be observed that the blocks do not fit the grooves tightly, but are cut away at the corners, as shown at 8, to permit the circulation of air through the roof structure, thereby preserving the wood, which- Inay a'lso be creosoted or otherwise treated for the same object. To afford the proper air The objects of the in` circulation, the edgesl of the Sheet 2 may be apertured or cut away in any suitable manner not shown. 'n A The sheetsy 2 are in standard` sizes and are connected along the sides by an overlapping,vv

interlocking slide joint, such as shown at l0, so that the sheets may expand and contract. At the ends of the sheets they are overlapped as shown in Figure 6, the blocks 6 terminating short of the sheets so as to permit the overlapping.

At suitable intervals, the structure is provided with means for attachment to the purlins y1. This is done by cutting apertures l1. inthe sheets at the edge of the purlin and inserting a fastener at each point. As shown in Figure 6, the fastener 12 is furnished to the workman as an L-shaped strip of metal which vis passed down'through the aperture 1l and under the flange of the purlin, and then bent over to its final cleating portion as shown in full lines in that figure. This form of fastener is easily applied by one workman and permits expansion and contraction of the sheets. It will be noted that the apertures 1l are somewhat wider' than the body of the clip, so that the clips do not interfere with the contraction and expansion of the sheets in a direction parallel to the channels. At the points where the fasteners are to be applied, the'blocks 6 are cut away as Shown and afterthe fastener is applied supplementary blocks 15 are dropped into the grooves over the fastener. These blocks are of the same configuration as the blocks 6, but are cut away at the bottom to accommodate the fastener. The sloping walls 5 support these short blocks adequately. Y

When the met-al base with the filler blocks has been laid over the purlins and Vfastened in the manner described, a cover 18 is placed over the metal foundation. This may be of any suitable material, but my form of roof structure is particularly adapted for the use of light, cheap and inexpensive material which cannot be used in the prior forms of roof structures.

What is claimed is:

l. In a roof structure, the combination'of flanged purlins, foundation sheets comprising a plurality of metal sheets having parallel channels, the sheets being laid over the purlins with overlapping edges parallel to the purlins, clips passed through the bases of the channels and over the flanges of the such sheets to purlins and to each other so as to permit expansion and contractiomwvood filler blocks in the channels, a sheet of reeling material over the metal sheets and secured to the filler blocks, a Waterproof covering thereon, and means for securinga circulation'of air along the filler blocks.

3. In af roof structure the combination of flanged purlins and a i'oundation comprising 15 a plurality of meta-l sheets having parallel channels,v the sheets being laid over the purlins with overlappingedges parallel to the purlins, the sheets being provided with apertures in the bottom of a channel through the overlapped portions arranged 'in register with the edges'of the flanged purlins, and Llp-shaped metal clips passed through the apertures7 one arm of each clip bearing against the underside of a flanged purlin and the other arm bearing against the upper surface of the upper sheet7` the apertures Deing Wider than the thickness of the clip so as 1to permit 'free contraction and expansion of the sheets. f
